Double-screw tug of 2 900 kW

DESIGN CHARACTERISTICS
The tug is intended for harbour assistance, moored ship's supply, long distance towing, firefighting and oil recovery. High degree of manoeuvrability is ensured by two 360° is rotative thrusters, each driven by one main engine. An advanced deck equipment, including forward and aft towing winches, towing hook, deck crane, workboat, foam/water monitors etc. will enable diverse and efficient operation.
